Timer

Her er min code, hvor jeg gerne vil ha en tid imellem de t steder hvor jeg sender en ulr af, nogle der kan hjælpe mig?

Public Class Web

    Public Shared Guide As String
    Public Shared convertprice As String
    Public Shared customer As String
    Public Sub Navigate(ByVal address As String)

        address = "http://qumec.com/components/com_virtuemart/order_price_modify.php?us=" + Guide + "&price=" + convertprice + "&userid=" + customer
       
Try
            Form1.WebBrowser1.Navigate(New Uri(address))       

' Hvordan sætter jeg en timer ind her imellem på 1 sek.?

            Form1.WebBrowser1.Navigate(New Uri(address))

        Catch ex As System.UriFormatException

            Return

        End Try

        Form1.WebBrowser1.Refresh()



        Form1.TextBox4.Text = Form1.TextBox4.Text + vbCrLf + address




    End Sub
End Class
